To all 107mm it may concern SIMoNs, a citizen of the Kingdom of the Netherlands, and resident ofthe city of lNeinheim, in the German Empire, and RU- DoLF KLEIN, a citizen of the Empire of invented new and useful improvements in Yielding Couplings, of which the following is a speciiication. Y

The present invention relates to an improvement in resilient couplings wherein the power transmission is obtained by means of blade springs, the latter being connected to Yone coupling member and bearing upon the lfaces of the other coupling member.

In known constructions of couplings of this kind the blade springs bear upon the driven face of a coupling member not at right angles to the direction of the peripheral force, and possess the drawbacks that the springs are influenced by lateral forces which result in rapid wear andl even fracture of the coupling. These couplings are therefore, not suitable for transmitting high power. The present invention eliminates this drawback by arranging the blade springs so that they are at right angles to the tangential periph-A eral force acting at their point of articulation on the coupling member. The lateral forcesl which do not act normally upon the springs, have their action eliminated or wholly avoided so that the wear and the danger of fracture are diminished as far as possible. To eliminate the wear which takes place owing to the sliding of the spring ends on the `driven face of the driven coupling member bringing the springs into action the coupling springs are formed, in accordance with the invention as-twin blade springs'and connected on both sides to the coupling members.

In the accompanying drawing two embodiments of the invention are shown.

Figures l and 2 show said two constructions of the coupling in end elevation. Fig. 3 is a side elevation of the coupling shown in Fig. 2 partly in section.

ln the embodiment shown in Fig. 1 of the drawing we use twin blade springs 8 and 9 which are connected to each other at their extremities. One part 8 of the springs is pvotally connected to the point 7 on the driving faces l of one coupling member or von thebearing'fplates Q'securedztheret'o while the other part 9of thespring is connected to the drivers 6 of thek coupling member 5. As is to be seen in Fig. l the springs 8 and 9 and Ialso the driving faces 6 of the clutch members 5 are arranged at right i angles to the resultant forces 0 acting tangentially" on the pivotal points 7 of the springs 8 on the other clutclr member. Lateral 'forces acting uponY the springs 8 and 9 cannot be created in this construction kso that the springs are normally influenced. The driving ribs l in the construction shown in Fig.V

1, are connectedwith the nave or hubofv its coupling member and in view of the additional resiliency provided by the yield of the twin springs upon themselves, shorter springs can be employed and the dia-meter of the coupling smaller without depreciating from the total resiliency of the coupling. In view of the stated advantages, the coupling shown `in Fig l is especially adapted for transmitting high power. 1

n the modification shown in Fig. 2 the link plates 10 of the spring carriers are eX- tended as sho-wn also in Fig. 3 behind the part 9 of the twin spring, and formed at the end with a slot 11 by means of which the said link plates are guided by the pins l2 of the other coupling member 5. The pins 12 are preferably arranged on the sides of the driving ribs 6 of the coupling member 5. Such guiding means may also be provided in the construction shown in Fig. 1.
